Hi Product Hunt! We built RoboPlay because most kids meet programming as text on a screen, while robots make the result physical: the rover slides on ice, slows on a hill, misses the bridge, and you fix the program because the world reacted, not because a checker said "wrong". How it works: Build: pick a robot (rover, tank, tractor, excavator, drone, helicopter... 14 in all) and fit motors, wheels, battery and sensors. Code: drag-and-drop blocks, with the same program shown as Python. After the Debugging lesson you can write Python by hand. Run: a deterministic 3D physics sim. Grip changes with the ground and the weather, wind pushes, batteries run down, Mars has low gravity. Debug: live sensor readings (distance, speed, surface, bumper), run block by block, then reach the goal for stars. What is inside: 25 missions in 7 chapters, a path of 36 lessons with hints in three steps, a Daily Challenge and an Endless mode, a scene editor to build your own levels, and English and Vietnamese throughout. The AI coach acts like a real teacher: it gives a hint, asks a question back and guides step by step instead of handing over the answer. It follows a school code of conduct, every answer can be reported in one tap, and nothing is sent until the student presses Ask. For teachers: classes with student sign-in by class code and PIN (no student emails), class progress with CSV export, levels assigned to a class, contests with a leaderboard, and a class board for announcements and homework. No ads, nothing to buy with real money. It runs in the browser; an Android tablet app is coming to Google Play. We would love feedback from parents, teachers and anyone who learned to code by breaking things. What should the next chapter be?
